SAFETY CONSIDERATIONS

Installation and servicing of air-conditioning equipment can

be hazardous due to system pressure and electric_d compo-

nents. Only trained and qualified service personnel should

install, repair, or service at>conditioning equipment.

Untrained personnel can perform basic maintenance func-

tions of cleaning coils and filters and replacing filters. All other

operations should be performed by trained service personnel.

When working on at>conditioning equipment, observe precau-

tions in the literature, tags and labels attached to the unit, and

other safety precautions that apply.

Follow all safety codes. Wear safety glasses and work

gloves. Use quenching cloth for unbrazing operations. Have

fire extinguishers available for all brazing operations.

Disconnect gas piping from unit when leak

testing at pressure greater than 1/2 psig. Pres-

sures greater than 1/2 psig will cause gas

valve damage resulting in hazardous condi-

tion. If gas valve is subjected to pressure

greater than 1/2 psig, it must be replaced

before use. When pressure testing field-

supplied gas piping at pressures of 1/2 psig

or less, a unit connected to such piping must

be isolated by manually closing the gas

valve.

Before performing service or maintenance operations on

unit, turn off main power switch to unit and install a lock-

out tag. Electrical shock could c_mse personal injury.

INSTALLATION

Unit is shipped in the vertical duct configuration. To convert

to horizont_d configuration, remove and save screws fi_m side

duct opening covers and remove covers. Using the same

screws, install covers on veriical duct openings with the

insulation-side down. Seals around duct openings must be

tight. See Fig. 1.

Confimt before installation of unit that voltage, mnperage

and circuit protection requirements listed on unit &tta plate

agree with power supply provided.

Step 1-- Provide Unit Support

ROOF CURB -- Assemble and install accesso Uroof curb in

accor&mce with instructions shipped with curb. See Fig. 2.

Install insulation, cant strips, roofing felt, and counter flashing

as shown. Ductwork must be attached to curb, not to the unit.

The accesso O"thru-the-boltom power and gas connection pack-

age must be installed b@re the unit is ,wt on the roo/ curb. If

field-installed (thin-the-roof curb) gas connections tue desired,

use factory-supplied 3/4-in. pipe coupling and gas plate assem-

bly to mount the thin-the-roof curb connection to the roof crag.

Gas connections and power connections to the unit must be

field installed after the unit is installed on the roof curb.

If electric and control wiring is to be routed through

the basepan, attach the accessory thru-the-bottom service

connections to the basepan in accordance with the accessory

installation instructions.

Manufacturer reserves the right to discontinue, or change at any time, specifications or designs without notice and without incurring obligations.

Catalog No. 04-53480014-01 Printed in U.S.A, Form 48T-5SI Pg 1 9-05 Replaces: 48T-3SI

IMPORTANT: Tile gasketing of tile unit to tile roof curb is ]

critical for a watertight seal. Install gasket supplied with the I

roof curb as shown in Fig. 2. hnproperly applied gasket can

result in tdr leaks and pool unit performance.

Curb should be level. Unit leveling tolerances are shown in

Fig. 3. This is necessary for unit drain to function properly.

Refer to Accessory Roof Curb Installation Instructions for

additional information as lequiled.

SLAB MOUNT (Horizontal Units Only) -- Provide a level

conclete slab that extends a minimum of 6 in. beyond unit

cabinet. Install a gravel apron in front of condenser coil air inlet

to prevent gross and foliage from obstructing airflow.

NOTE: Horizontal units may be installed on a roof curb if

required.

ALTERNATE UNIT SUPPORT (Curb or Slab Mount) -- A

non-combustible sleeper rail can be used in the unit curb sup-

port tuea. If sleeper rails cannot be used, support the long sides

of the unit with a minimum of 3 equally spaced 4-in. x 4-in.

pads on each side.

Step 2 -- Field Fabricate Ductwork -- Secure all

ducts to roof curb and building structure on vertical ducted

units. Do not connect du(_'ork to unit. For horizontal applica-

tions, field-supplied flanges should be attached to horizontal

duct openings and all ductwork should be secured to the

flanges. Insulate and weatherproof all external ductwork,

joints, and roof openings with counter flashing and mastic in

accor&mce with applicable codes.

Ducts passing through an unconditioned space must be

insulated and covered with a vapor b_uriel:

If a plenum return is used on a vertical unit, the return

should be ducted through the roof deck to comply with applica-

ble fire codes.

A minimum clearance is not required around ductwork.

Cabinet return air static pressme (a negative condition) shall

not exceed 0.35 in. wg with economizer or 0.45 in. wg without

economizeE

These units tue designed for a minimum continuous heating

return-air temperature of 50 F (dry bulb), or an intermittent

operation down to 45 F (@ bulb), such as when used with a

night set-back thermostat. To operate at lower return-air tem-

peratures, a field-supplied outdoor air temperature control must

be used to initiate both stages of heat when the temperature is

below 45 E Indoor comfort may be compromised when these

lower air temperatures are used with insufficient heating tem-

perature rise.

Step 3 -- Install External Trap for Condensate

Drain -- The unit's 3/4-in. condensate drain connections are

located on the bottom and side of the unit. Unit discharge con-

nections do not deterraine the use of drain connections; either

dnun connection can be used with vertic;d or horizont;d

applications.

When using the standard side &'ain connection, make sure

the plug (Red) in the ;alternate bottom connection is tight before

inst;dling the unit.

To use the bottom drain connection for a roof curb installa-

tion, relocate the factory-installed plug (Red) from the bottom

connection to the side connection. The center &'ain plug looks

like a stm"connection, however it can be removed with a l/2-in.

socket drive extension. See Fig. 4A. The piping for the conden-

sate &'ain and external trap can be completed after the unit is in

place. See Fig. 4B.

All units must have an exWrnal trap./(_r condensaW druin-

age. Instull a tru l) at least 4-in. deep and prowct against fi'eeze-

Ul). I/ drain line is installed downstmam /?om the exWrlml trap,

pitch the fine awayfl'om the unit at 1 in. per lOft q/run. Do not

use a pipe s£e smaller than the unit connection (J/4 in.).

Fig. 6B -- Base Unit Dimensions -- 48TM007

Do not install unit in an indoor location. Do not locate unit

air inlets near exhaust vents or other sources of contalninated

all:

Be sure that unit is installed such that snow will not block

the combustion intake or flue outlet.

Unit may be installed directly on wood flooring or on

Class A, B, or C roof-covering material when roof curb is used.

Although unit is weatherproof, guard against water fiom

higher level runoff and overhangs.

Flue vent dischaqq, e must have a minimum hoH;ontul clear-

ance qf4 fi,fmm elecTHc and gas mewrs, gas mgulawt:_, and

gas milerequipment.

Minimum distance between unit and other electrically live

parts is 48 inches.

Flue gas can deteriorate building materials. Orient unit

such that flue gas will not affect building materials. Locate

mechanical draft system flue assembly at least 48 in. fiom an

adjacent building or combustible materi_d.

Adequate combustion-air and ventilation-air space must be

provided for proper operation of this equipment. Be sure that

installation complies with all local codes and Section 5.3, Air

for Combustion and Ventilation, NFGC (National Fuel Gas

Code), and ANSI (American National Stan&rds Institute)

Z223.1, and NFPA (National File Protection Association)

54 TIA-54-84-1. In Cana&t, installation must be in accordance

with the CANI-BI49 inst_dlation codes for gas burning

appliances.

After unit is in position, remove rigging skids and shipping

materials.

Step 5 -- Install Flue Hood -- Flue hood is shipped

screwed to the basepan beside the burner compmlment access

panel. Remove from shipping location and using screws pro-

vide& install flue hood and screen in location shown in Fig. 7.

Step 6 -- Install Gas Piping -- Unit is equipped for

use with type of gas shown on nameplate. Refer to local build-

ing codes, or in the absence of local codes, to ANSI Z223.1

entitled National Fuel Gas Code. In Cana&t, installation must

be in accordance with the CANI.BI49A and CANI.BI49.2

installation codes for gas burning appliances.

For natural gas applications, gas pressuw at unit gas con-

nection must not be less titan 4 in. wg or greaWr than

13.0 in. wg while unit is operating. On 48TF005,006,007 high

heat units, the gas pressure at unit gas connection must not be

less than 5 in. wg or greater than 13 in. wg while the unit is

operating. For propane applications, the gas pressure must not

be less than 5 in. wg or greater than 13 in. wg at the unit

connection.

Size gas supply piping .fbr 0.5 in. wg maximum pressure

drop. Do not use supply pipe smNler titan unit gas connection.

Support gas piping as shown in the table in Fig. 8. For exam-

ple, a 3h-in. gas pipe must have one field-fabricated support

beam every 8 ft. Therefore, an 18-1l long gas pipe would have a

minimum of 2 support beams, a 48-ft long pipe would have a

minimum of 6 support beams.

See Fig. 8 for typical pipe guide and locations of external

manual main shutoff valve.

When connecting the gas line to the unit gas valve, the

installer MUST use a backup wrench to prevent damage to

the v_flve.

Step 7 -- Make Electrical Connections

Unit cabinet must have tin uninterrupted, unbroken electri-

cal ground to minimize the possibility of persomd injury if

an electrical fault should occm: This ground may consist of

electrical wire connected to unit ground lug in control com-

ptu-tment, or conduit approved for electrical ground when

insttdled in accordance with NEC (National Electrical

Code), ANSI/NFPA, latest edition, and local electrical

codes. Do not use gas piping as an electrical ground. Fail-

ure to follow this warning could result in the installer being

liable for personal injury of others.

FIELD POWER SUPPLY -- All units except 208/230-v

units are factory wired for the voltage shown on the nameplate.

If the 208/230-v unit is to be connected to a 208-v power sup-

p13; the tran_fin'mer must be rewired by moving the black wire

with the//4-in, fi, male .s)ga_e connecwr fi'om the 230-volt _on-

nection and moving to the 200-volt l/4-in, mule terminal on the

prima 0" sMe of the tran@n'mel:

Refer to unit label diagrmn for additional information. Pig-

tails are provided for field wire connections. Use factory-

supplied splices or UL (Underwriters' Laboratories) approved

copper/aluminum connector

When installing units, proffde a dis_ onnect per the NEC.

All .field wiring must comply with NEC and lotzd

requirements.

Install field wiring as follows:

1. Install conduit through side panel openings. Install con-

duit between disconnect and control box.

2. Install power lines to terminal connections as shown in

Fig. 9.

Voltage to compressor terminals during operation must be

within voltage range indicated on unit nameplate (see Tables 2A

and 2B). On 3-phase units, voltages between phases must be

bahmced within 2% and the currant within 10%. Use the formu-

la shown in the legend for Tables 2A and 2B, Note 2 to deter-

mine the percent of voltage imbalance. Operation on improper

line voltage or excessive phase imbalance constitutes abuse and

may cause dmnage to electrictd components. Such operation

would invali&tte any applicable Carrier wammty.

FIELD CONTROL WIRING -- Install a Carrier-apl)roved

acc'essoiw thermostat assembly according to installation

instructions included w#h the accessolw Locate thermostat

assembly on a solid wall in the conditione_l space to sense aver-

age temperature in accor&mce with thermostat installation in-

structions. Connect thermostat wires to terminal board.

Route thermostat cable or equivalent single leads of colored

wire from subbase terminals through connector on unit to low-

voltage connections (shown in Fig. 10).

NOTE: For wire runs up 50 ft, use no. 18 AWG (American

Wire Gage) insulated wire (35 C minimum). For 50 to 75 ft,

use no. 16 AWG insulated wire (35 C minimum). For over

75 It, use no. 14 AWG insulated wire (35 C minimum). All

wire larger than no. 18 AWG cannot be directly connected to

the thermostat and will require a junction box and splice tit the

thermostat.

Pass the control wires through the hole provided in the cor-

ner post; then feed wires through the raceway built into the

corner post to the 24-v barrier located on the left side of the

control box. See Fig. 11. The raceway provides the UL

required clearance between high and low-voltage wiring.

HEAT ANTICIPATOR SETTINGS -- Set heat anticipator

settings tit 0.14 amp for the first stage and 0.14 amp for second-

stage heating, when available.

NOTES:

1. In compliance with NEC requirements for multimotor and combination load equipment

(refer to NEC Articles 430 and 440), the overcurrent protective device k)r the unit shall

be fuse or HAOR breaker. Canadian units may be fuse or circuit breaker.

2. Unbalanced 3-Phase Supply Voltage

Never operate a motor w6ere a phase imbalance in supply voltage is greater than 2%.

Use the following formula to determine the percent of voltage imbalance.

% Voltage Imbalance

= 100 x max voltage deviation from average voltage

average voltage

Example: Supply voltage is 460-3-60.

AB = 452 v

AB C BC =464v

AC = 455 v

Average Voltage = 462 + 464 + 455

1371

= 457

Determine r'aaximum deviation from average voltage.

(AB) 457 - 452 = 5 v

(BC) 464 - 457 = 7 v

(AC) 457 - 455 = 2 v

Maxir'aum deviation is 7 v.

Detemline percent of voltage imbalance.

% Voltage Imbalance = 100 x -- 457

= 1.53%

This amount of phase imbalance is satisfactory as it is below the maximum alk)wable

2%.

IIMPORTANT: If the supply voltage phase imbalance is more than 2%, contact I

your local electric utility company immediately. I

3. For units with power exhaust: If a single power source is to be used, size wire to include

power exhaust MCA and MOOR Check MCA and MOCP when power exhaust is pow-

ered through the unit (must be in accordance with NED and/or local codes). Determine

the new MCA including the power exhaust using the following formula:

MCA New = MCA unit only + MCA of Power Exhaust

For example, using a 48TF006---5 unit with MCA = 28.9 and MOCP = 35, with

CRPWREXH080A00 power exhaust.

MCA New = 28.9 amps + 1.6 amps = 30.5 amps

If the new MCA does not exceed the published MOCP, then MOCP would not change.

The MOOP in this example is 35 amps, the MCA New is below 35, therefore the MOCP

is acceptable. If "MCA New" is larger than the published MOOP, raise the MOCP to the

next larger size. For separate power, the MOCP for the power exhaust will be 15 amps

per NEC.

PREMIERLINK TM CONTROL -- The PremierLink control-

let is compatible with Carrier Comfo]l Network® (CCN) de-

vices. This control is designed to allow users file access and

ability to change factory-defined settings, thus expanding the

function of file standm'd unit control board. Career's diagnostic

standard tier display tools such as Navigator TM or Scrolling

Marquee can be used wifll the PremierLink controlle]:

The PremielLink controller (see Fig. 16A and 16B) requires

the use of a Carrier electronic thermostat or a CCN connection

for time broadcast to initiate its internal timeclock. This is

necessmy for broadcast of time of &ty functions (occupied/

unoccupied). No sensors me supplied with the field-mounted

PremierLink control. The factory-installed PremierLink con-

trol includes only the supply-air sensor (SAT) and the outdoor

air temperature sensor ((-)AT) as stan&trd. An indoor air quality

(CO2) sensor can be added as tin option. Refer to Table 3 for

sensor usage. Refer to Fig. 17 for PremierLink controller

wiring. The PmmierLink control may be mounted in file

control panel or an area below the control panel.

NOTE: PmmierLink controller versions 1.3 and later am

shipped in Sensor mode. If used with a fllermostat, the Pre-

mierLink controller must be configured to Themiostat mode.

Install the Supply Air Temperature Sensor (SAT) -- When

the unit is supplied with a factory-mounted PremierLink con-

trol, the supply-air temperature (SAT) sensor (33ZCSENSAT)

is factory-supplied and wimdi The wiring is routed from the

PmmierLink control over the control box, through a grommet,

into the fan section, down _flong the back side of the fan, and

along the fan deck over to the supply-air opening.

The SAT probe is wire-tied to the supply-air opening (on the

horizontal opening end) in its shipping position. Remove the

sensor for installation. Re-position the sensor in the flange of

the supply-air opening or in the supply air duct (as required by

local codes). Drill or punch a l/2-in, hole in the flange or duct.

Use two field-supplied, self-drilling screws to secure the sensor

probe in a horizontal orientation.

NOTE: The sensor must be mounted in the dischmge airstream

downstream of the cooling coil and any heating devices. Be

sure the probe tip does not come in contact with tiny of the unit

or heat surfaces.

Outdoor Air Temperature Sensor (OAT) -- When the unit is

supplied with a factoq-mounted PremierLink control, the

outdoor-air temperature sensor (OAT) is factory-supplied and

wired.

Install the Indoor Air Quality (COp) Sensor -- Mount the

optional indoor air quality (CO2) sensor according to manufac-

turer specifications.

A separate field-supplied transformer must be used to pow-

er the CO2 sensor

Determine the EconoMiSer IV control mode before set up of

file control. Some modes of operation may require different sen-

sors. Refer to Table 5. The EconoMiSer IV is supplied from the

facto qwith a supply air temperature sensor and an outdoor air

temperature sensol: This allows for operation of the

EconoMiSer IV with outdoor air dry bulb changeover control.

Additional accessories can be added to allow for different types

of changeover control and operation of the EconoMiSer IV and

unit.

Outdoor DLy Bulb Changeover -- The standard controller is

shipped from the facto qconfigured for outdoor @ bulb

changeover control. The outdoor air and supply air temperature

sensors me included as standmd. For this control mode, the

outdoor temperature is compared to an adjustable set point

selected on file control. If the outdoor-air temperature is above

file set point, file EconoMiSer IV will adjust the outdoor-air

dampers to minimum position. If the outdoor-air temperature is

below the set point, the position of the outdoor-air &tmpers will

be controlled to provide flee cooling using outdoor till: When

in this mode, the LED next to the free cooling set point potenti-

ometer will be on. The changeover temperature set point is

controlled by the free cooling set point potentiometer located

on the control. See Fig. 33. The sc_de on the potentiometer is A,

B, C, and D. See Fig. 34 for the corresponding temperature

changeover values.

Differential DLy Bulb Control -- For differential dly bulb

control the stan&ud outdoor dry bulb sensor is used in conjunc-

tion with an additional accesso Uch7 bulb sensor (part number

CRTEMPSN002A00). Tile accessory sensor must be mounted

in the return airstream. See Fig. 35. Wiring is provided in the

EconoMiSer [V wiring harness. See Fig. 27.

In this mode of operation, the outdoor-tfir temperature is

compared to the leturn-air temperature and the lower tempera-

ture tfirstream is used for cooling. When using this mode of

changeover control, turn the enth_dpy setpoint potentiometer

fully clockwise to the D setting. See Fig. 33.

Outdoor Enthalpy Changeover -- For enthalpy control, ac-

cessory enthalpy sensor (p_ut number HH57AC078) is re-

quired. Replace the standard outdoor chy bulb temperature sen-

sor with the accessory enthalpy sensor in the same mounting

location. See Fig. 20. When the outdoor air enthalpy rises

above the outdoor enthalpy changeover set point, the outdoor-

air damper moves to its minimum position. The outdoor

enthalpy changeover set point is set with the outdoor enthalpy

set point potentiometer on the EconoMiSer IV controller The

set points are A, B, C, and D. See Fig. 36. The factory-installed

620-ohm jumper must be in place across terminals SR and SR+

on the EconoMiSer IV controllec See Fig. 20 and 37.

Differential Enthalpy Control -- For differential enthalpy

control, the EconoMiSer IV controller uses two enthalpy sen-

sors (HH57AC078 and CRENTDIF004A00), one in the out-

side air and one in the leturn air duct. The EconoMiSer [V

controller comptues the outdoor air enthalpy to the return air

enthalpy to determine EconoMiSer IV use. The controller

selects the lower enth_dpy air (return or outdoor) for cooling.

For example, when the outdoor tfir has a lower enthalpy than

the return tfir. the EconoMi$er IV opens to bring in outdoor air

for free cooling.

Replace the standard outside air dUbulb temperatme sen-

sor with the accessory enthalpy sensor in the same mounting

location. See Fig. 20. Mount the return air enthalpy sensor in

the leturn air duct. See Fig. 35. Wiring is provided in the

EconoMiSer IV wiring harness. See Fig. 27. The outdoor en-

thalpy changeover set point is set with the outdoor enthalpy set

point potentiometer on the EconoMiSer IV controllen When

using this mode of changeover control, turn the enthalpy set-

point potentiometer fully clockwise to the D setting.

DAMPER VOLTAGE FOR MAX VENTILATION RATE

Fig. 38 -- CO2 Sensor Maximum Range Setting

Exhaust Set Point Adjustment -- The exhaust set point will

determine when the exhaust fan runs based on dmnper position

(if accessory power exhaust is installed). The set point is modi-

fied with the Exhaust Fan Set Point (EXH SET) potentiometer

See Fig. 33. The set point represents the damper position above

which the exhaust fans will be turned on. When there is a call

for exhaust, the EconoMiSer IV controller provides a 45 _+15

second delay before exhaust fan activation to allow the damp-

ers to open. This delay _fllows file damper to reach the appro-

priate position to avoid unnecessaly fan overload.

Minimum Position Control -- There is a minimum damper

position potentiometer on the EconoMiSer [V controllel: See

Fig. 33. The minimum damper position maintains the mini-

mum airflow into the building during the occupied period.

When using demand ventihttion, the minimum dmnper po-

sition represents the minimum ventilation position for VOC

(volatile organic compound) ventilation requirements. The

maximum demand ventilation position is used for fully occu-

pied ventilation.

When demand ventilation control is not being used, the

minimum position potentiometer should be used to set the oc-

cupied ventilation position. The maximum demand ventilation

position should be turned fully clockwise.

Adjust the minimum position potentiometer to allow the

minimum mnount of outdoor aik as required by local codes, to

enter the building. Make minimum position adjustments with

at least 10 F temperature difference between the outdoor and

return-air temperatures.

To determine the minimum position setting, perform the

following procedure:

1. Calculate the appropriate mixed air temperature using the

following formula:

OA RA

(Tox I--F6_) +(TRx 1-Tff6-)=TM

To = Outdoor-Air Temperature

OA = Percent of Outdoor Air

TR = Return-Air Temperature

RA = Percent of Return Air

TM = Mixed-Air Temperature

As an example, if local codes require 10% outdoor tdr

during occupied conditions, outdoor-air temperature is

60 E and return-air temperature is 75 E

(60 x .10) + (75 x .90) =73.5 F

2. Disconnect the supply air sensor from terminals T and

TI.

3. Ensure that the factou-installedjumper is in place across

terminals P and PI. If remote damper positioning is being

used, make sure that the terminals am wired according to

Fig. 27 and that the minimum position potentiometer is

turned fully clockwise.

4. Connect 24 vac across terminals TR and TRI.

5. CarefiJlly adjust the minimum position potentiometer

until the measured supply air temperature matches the

calculated value.

6. Reconnect the supply _firsensor to termimds T and TI.

Remote control of the EconoMi$er IV damper is desirable

when requiring additiomd temporm-y ventilation. If a

field-supplied remote potentiometer (Honeywell part number

$963B1128) is wired to the EconoMi$er IV controllek the

minimum position of the damper can be controlled from a m-

mote location.

To control the minimum damper position remotely, remove

the factory-installed jumper on the P and PI terminals on the

EconoMi$er IV controllel: Wire the field-supplied potentiome-

ter to the P and PI terminals on the EconoMi$er IV controller.

See Fig. 37.

Damper Movement -- Damper movement trom full open to

full closed (or vice versa) takes 2112minutes.

Thermostats -- The EconoMiSer IV control works with con-

ventiomd thermostats that have a YI (cool stage 1), Y2 (cool

stage 2), Wl (heat stage 1), W2 (heat stage 2), and G (fan). The

EconoMiSer IV control does not support space temperature

sensors. Connections are made at the thermostat termimd con-

nection board located in the main control box.

Occupancy Control -- The factoUdefault configuration for

the EconoMi$er IV control is occupied mode. Occupied status

is provided by the black jumper flom terminal TR to terminal

N. When unoccupied mode is desired, inst_dl a field-supplied

timeclock function in place of the jumper between TR and N.

See Fig. 27. When the timeclock contacts are closed, the

EconoMi$er IV control will be in occupied mode. When the

timeclock contacts are open (removing the 24-v signal from

terminal N), the EconoMi$er IV will be in unoccupied mode.

Demand Controlled Ventilation (DCV) -- When using the

EconoMiSer IV for demand controlled ventilation, them are

some equipment selection criteria which should be considered.

When selecting the heat capacity and cool capacity of the

equipment, the maximum ventilation rote must be evaluated for

design conditions. The maximum damper position must be cal-

culated to provide the desired fresh ail:

Typically the maximum ventilation rate will be about 5 to

10% morn than the typical chn required per person, using nor-

mid outside air design criteria.

A proportional anticipatory strategy should be taken with

the following conditions: a zone with a large area, varied occu-

pancy, and equipment that cannot exceed the required ventila-

tion rate at design conditions. Exceeding the required ventila-

tion rate means the equipment can condition air at a maximum

ventilation rate that is greater than the required ventilation rate

for maximum occupancy. A proportional-anticipato Ustrategy

will cause the fresh air supplied to increase as the room CO2

level increases even though the CO2 set point has not been

reached. By the time the CO2 level roaches the set point, the

damper will be at maximum ventilation and should maintain

the set point.

In order to have the CO2 sensor control the economizer

damper in this manner, fil.'stdetermine the damper voltage out-

put for minimum or base ventilation. Base ventilation is the

ventilation required to remove contmninants during unoccu-

pied periods. The following equation may be used to determine

the percent of outside-air entering the building for a given

damper position. For best results there should be at least a

10 degree difference in outside and return-air temperatures.

OA RA

(To x l-T-ff_) + (TR x _ ) = TM

To = Outdoor-Air Temperature

OA = Percent of Outdoor Air

TR = Return-Air Temperature

RA = Percent of Return Air

TM = Mixed-Air Temperature

Once base ventilation has been determined, set the mini-

mum damper position potentiometer to the correct position.

The same equation can be used to deterlnine the occupied or

maximum ventilation rate to the building. For example, an out-

put of 3.6 volts to the actuator provides a base ventilation rate

of 5% and an output of 6.7 volts provides the maximum venti-

lation rate of 20% (or base plus 15 cfm per person). Use Fig. 38

to determine the maximum setting of the CO2 sensol: For ex-

ample, a 1100 ppm set point relates to a 15 cfm per person de-

sign. Use the 1100 ppm curve on Fig. 38 to find the point when

the CO2 sensor output will be 6.7 volts. Line up the point on the

graph with the left side of the chart to determine that the range

configuration for the CO2 sensor should be 1800 ppm. The

Dehumidification of Fresh Air with DCV Control -- Infor-

mation from ASHRAE indicates that the largest humidity load

on any zone is the fresh air introduced. For some applications,

a device such as a 62AQ energy recovery unit is added to re-

duce the moisture content of the fresh air being brought into the

building when file enthalpy is high. In most cases, the normfd

heating and cooling processes are morn than adequae to m-

move the humidity loads for most commemial applications.

If normal rooftop heating and cooling operation is not ade-

quate for the outdoor humidity level, fin energy recovery unit

and/or a dehumidification option should be considered.

Step 9 -- Adjust Evaporator-Fan Speed -- Ad-

just evaporator-fan rpm to meet jobsite conditions. Table 7

shows ffm rpm at motor pulley settings. Table 8 shows motor

performance. See Table 9 for accessory and option static pres-

sure drops. See Table 10 for evaporator-fan motor efficiency.

Refer to Tables 11-40 to determine fan speed settings.

DIRECT-DRIVE MOTORS-- The evaporator-fan motor

factory speed setting is shown on label diagram affixed to base

unit. If other than factory setting is desired, refer to label

diagram for motor reconnection. See Fig. 39 for direct-drive

motor location.

BELT-DRIVE MOTORS- Fan motor pulleys are factory

set for speed shown in Tables IA and lB. See Fig. 40 for belt

di'ive motor location.

NOTE: Before adjusting fan speed, make sure the new ffm

speed will provide an air temperature rise range as shown in

Tables IA find lB.

To change fan speed:

1. Shut offunit power supply.

2. Ix_osen belt by loosening fan motor mounting nuts. See

Fig. 40.

3. Ix_osen movable pulley flange setscrew (see Fig. 41 ).

4. Screw movable flange toward fixed flange to increase

speed and away from fixed flange to decrease speed.

Increasing fan speed increases load on motol: Do not

exceed maximum speed specified in Tables IA find lB.

5. Set movable flange fit nearest keyway of pulley hub and

tighten setscrew. (See Tables 1A find 1B for speed change

for each fifll turn of pulley flange.)

To align fan and motor pulleys:

1. Ix_osen fan pulley setscrews.

2. Slide fan pulley along fan shaft.

Make angulm alignment by loosening motor from

mounting.
